Drought conditions in Georgia worsen dramatically in August
By David E. Stooksb ury University of Georgia

Drought conditions across Georgia have worsened dramatically since the beginning of August. Widespread triple-digit high temperatures and very little rain have caused soil moisture levels to plummet, stream flows to approach record lows and groundwater and lake levels to drop sharply.

(Wilkes County is now said to be in extreme drought, one level below the worst condition.)

In late August, of Georgia's 159 counties, drought conditions were classified as exceptional in 70, extreme in 40, severe in 15, moderate in 13 and mild in six, with 11 counties classified as abnormally dry. Four counties are classified as not being in drought.

In early August, drought conditions were exceptional in 37 counties, extreme in 55, severe in 16, moderate in 21 and mild in 10, with eight abnormally dry. Twelve counties were classified as not being in drought.

In late June, no counties were in exceptional drought, but conditions were extreme in 104 and severe in 38. Then, conditions were moderate in just 15 and mild in only two, and no county was just abnormally dry or not in drought.

Drought conditions are expected to be "exceptional" about once in 100 years, "extreme" once in 50 years and "severe" once in 20 years. The classifications are based on many indicators, including rainfall since Oct. 1 and over the past 180, 90, 30 and 14 days, soil moisture, stream flows, groundwater levels and reservoir levels.

Counties in exceptional drought are in southwest and north Georgia. The 19 southwestern counties are west of a line through, and including, Thomas, Colquitt, Mitchell, Dougherty, Lee, Terrell, Webster, Marion and Stewart.

In north Georgia, the 51 counties classified as in exceptional drought are north of a line through, and including, Troup, Meriwether, Pike, Spalding, Henry, Newton, Walton, Oconee, Clarke, Madison and Franklin.

Extreme drought conditions are in west-central and south-central Georgia and the south central and southeastern piedmont. In west central Georgia, Bibb, Chattahoochee, Crawford, Harris, Lamar, Marion, Monroe, Muscogee, Peach, Schley, Talbot, Taylor and Upson counties are classified as in extreme drought.

In south-central Georgia, the counties in extreme drought are Berrien, Brooks, Cook, Crisp, Dooly, Echols, Irwin, Lanier, Lowndes, Sumter, Tift, Turner and Worth.

In the south-central and southeastern piedmont, the counties in extreme drought are Baldwin, Butts, Elbert, Greene, Hancock, Hart, Jasper, Jones, Lincoln, Morgan, Oglethorpe, Putnam, Taliaferro and Wilkes.

Severe drought conditions are found in Atkinson, Ben Hill, Burke, Clinch, Coffee, Columbia, Glascock, Houston, Jenkins, McDuffie, Pulaski, Richmond, Screven, Warren and Wilcox counties.

Moderate conditions are in Bacon, Bleckley, Bulloch, Dodge, Effingham, Evans, Jeff Davis, Jefferson, Telfair, Twiggs, Ware, Washington and Wilkinson counties.

And mild conditions exist in the coastal counties of Bryan, Camden, Chatham, Liberty, McIntosh and Glynn.

The counties classified as abnormally dry are Appling, Brantley, Candler, Charlton, Emanuel, Johnson, Long, Pierce, Tattnall, Toombs and Wayne.

The four counties not classified as in drought - Laurens, Montgomery, Treutlen and Wheeler - got beneficialrains from the remnants of tropical storm Barry and continue to get timely and bountiful rains.

However, even the counties where the drought is now mild or better could see conditions deteriorate quickly if temperatures remain high and timely rains fail to materialize.

High temperatures combined with little rainfall will result in the soil drying quickly and plants becoming stressed.

Soil moisture is near the 1st percentile across most of west and north Georgia. At this level, we would expect the soil to be moister in 99 of 100 years.

Soil moisture loss to evaporation and plant use is now running between one-quarter and one-third of an inch per day.

No widespread relief is foreseeable. In August and September, the best hope for widespread drought relief is from tropical weather systems. Without these, we can expect the drought to worsen over the next two months.
